SHOE

Original Filed July 25, 1942 INVENTOR Daw/N/cn l/ Owe/M220 E PATTORNEY a of manufacturing playshoes by providing outvidean outsole-midsole combination and method obvious andin part hereinafter pointed out.

plified in the constructions hereinafter described,

Said combination l consists of a midsole l2 and Patented Dec. 18, 1945 U L -';-,-H II STATES OFFICE? Original application July 25,1942, SerialyNo. 452,312. Divided" and this application April 30, 1943, Serial No.-485,110 I r e 1 6 Claims. (01. 36-30 I V v The midsole 12 is a-thicklayer I 6 of a felted substance whose edges are covered by an ornamental binding 18 attachedto the midsole by a line of stitching 20. The peripheral contour of the midsole generally approximates a bottom plan of the shoe,so that the midsole may be said to consist of a midsole fore portion 22, a midsole heel portion 24, and a midsole shank portion 26 between the midsole fore and heel portions.

I'his inventionrelates to shoes. More particularly, the invention pertains to outsoles and to outsole-midsole combinations which are adapted to be used in playshoes such as shown and described in my copending application, Serial No. 452,312, filed July 25, 1942, of which the present application is a division. vAri-object of the invention is to reduce the cost soles which extend predominantly over only the foreportions of shoes as contrasted with outsoles heretofore used-in playshoes which covered either the entire bottom surfaces of the shoes, including not only the fore portions but the shanks and heels as Well, or covered the bottom surfaces of the shoes including the entire shanks and extended up to the heels. Another object of the invention is to provide a playshoe in which a preset and pretrimmed outsole is used with resulting increase in speed of production and saving of material.

Anadditional object of the invention is to proing or fore portion 28 of the same peripheral contour as the midsole fore portion 22. Extending rearwardly from said outsole wearing portion 28 is a stub shank portion 3|] of full width; i. e. conforming in outline to that part of the midsole shank portion 26 immediately behind the midsole fore portion 22. As its name implies, said stub shank terminates short of the heel portion of the midsole. A short extension 32, skived to a thin rear edge 34, extends from the back'of the stub. shank 3 0 stopping short of the heel of the midsole, said extension being of reduced width, i. e. narrower than the corresponding part of the midsole shank portion 26. v

'The outsole l4 is pretrimmed to the foregoing final shape and dimensions and the extension 32 preoutbefore the outsole is attached to any other element of a shoe. Thereby, I am able to expedite and cheapen the manufacture of the out- 9 sole and avoid either pretrimming or precutting near the ornamental binding IB of the midsole where greater, care must be exercised.

I also preset the rim of the outsole. This may be done by disposing the outsole transversely of a horizontal inking roll which is freely rotatably mounted on supports and is partially immersed in an inking bath. A portion of the outsole rim is contacted with the exposed surface of the roll and the outsole revolved While contact with the roll is maintained whereby to color the entire rim. The frictional engagement between the outsole and roll turns the roll and causes a of making the same which facilitates subassembly-pf the shoe and thus simplifies the manufact-llre. 1 I I --Other objectsof this invention will in part be j 1 Thelinvention accordingly consists in the featuresof construction, combination of elements, and arrangement, of parts which will be exemand of which the scope of application will be indicated in the claims.

Referring now to the drawing and more particularly to Figs. 1 through 5, I have there shown a. midsole-outsole combination Hl embodying my invention and adapted to be used in the construction of a playshoe such as is shown and described in my aforesaid copending application.

'to the;outsole.-"The colored rim is then set by shining, and, if desiredmay beg-lazed and buffed.

The outsole, after pretrimming, precutting, and presetting, is placed on the midsole with its rim in registry with the rim of the corresponding midsole parts, to wit, the midsole fore portion and adjacent part of the midsole shank portion. The outsole is then attached to the midsole by a metallic fastener, such as a staple 36, whose points are clenched in the midsole.

The outsole-midsole combination is now fully prepared as a finished subassembly and may be an outsole l4.

The outsole I4 comprises in the main a wearfreshly inked surface to be constantly presented outsole l4. Said outsole 38 comprises a Wearing portion 40 and stub shank portion 42 similar to the wearing and stub shank portions 28, 30 heretofore described. The extension 44, however, comprises a narrow tab, of lesser width than the corresponding part of the midsole shank portion 26, which projects from the rearof the stubshank 42 It will thus be seen that there is provided an I article and method for making and using the same in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
